27 Claims. (c1. 299-68) l My invention relates to a waterv sprinklingdevice that is especially designed for use on lawns, golf courses,gardens, orchards or wherever a thorough distribution of water isdesired overa relatively large area and the principal objects of myinvention are, to generally improve upon and simplify the constructionof the .existing forms of rotary Water sprinklers and to provide asprinkler of the rotary type that is relatively simple in construction,inexpensiveA of manufacture and which willbe very effective inperforming the functions for which it is intended.

Further objects of my invention are, to provide a water sprinkler,wherein the housing that carries the jet nozzle is caused to slowlyrotate about its axis as a result of the impingelnenty of a relativelysmall jet of water against a wheel having radially disposed blades andwhich wheel functions for the distribution of water throughout the areaimmediately adjacent to the point where the sprinkler is positioned,further, to provide a sprinkler having a housing within which Vareformed separate chambers, one of which Ycontainsv the vertical bearingsfor the housing and also the gearing that is utilized for impartingrotary motion to said housing, the other chamber functioning as a watercirculation chamber and having jet nozzles projecting therefrom andfurther, to provide simple and eflicient means for controlling the jetof water that impinges against vthe blades of the Water spreading wheeland likewise for controlling the pressure and force of said jet ofwater.

Further objects of my invention are, to provide a sprinkler of thecharacter referred to having a separate water chamber that is connectedto the source of supply and from which projects the main jet nozzle, toprovide simple and eflicient means within said Water chamber forproducing, aY perfect bala-nce of thethrust resulting from theV pressureof the water passing through said chamber and further, to provide animproved construction wherein Wear between moving parts of the rotatinghousing vand the gearing container therein is minimized.

. A further object of my invention is, to provide improved packings forthe bearings between the v Water housing and its support so as topracticallyeliminate `the possibility of the development of weariii-said bearings as a result of the presence of sand, grit and the likethat passes through the sprinkler with the Water that is delivered toand discharged therefrom.

A further objectof my invention is, toprovide a lrotary sprinkler havingrelatively simple'land efficient means whereby the necessary adjustmentsmay be made so as to cause said sprinkler to operate at highest efciencyunder all conditions of variable water pressure, speed-of rotation ofthe nozzle carrying head and the variable areas to be covered by theWater that is discharged from the rotary head.

Referring by numerals to the accompanying drawingswhich illustrate apractical embodiment of my invention, 10 designates a housing preferablycast from metal and which housing is mounted between the upper portionsof a pair of runnersY 11. having upturned ends 12, thus enablingY thebase structure and Ythe parts carriedthereby to be readily drawn overthe surface of the ground and consequently permitting thesprinkler to bereadily shifted from one position to another.

Projecting from the upper portion of-housing 10 is a connection 13 for asupply `pipe or hose 14 and arranged in the lower portion of the sidewall of housing l0 is a removable plug lowhich permits access to theinterior of the housing. in order that accumulations such as sandand'siltmay be lso means of a plug 18 that is screwed into the lowerportion of said tubular post and the lower portion of which plug bearsagainst the bottom Wall of housing 10.

Suitable packing rings 19 are arranged between plug 18 and the bottom ofhousing 1) and likewise between the top of said housing and a shoulderthat is formed on the tubular standardl'l.

Thewall of the tubular standard 17, within the chamber 18 in housing 10,is' perforated as designated by 20, and surrounding this perforatedportion of the standard and spaced apart therefrom is a concentricallyarranged perforated strainer 21. This strainer is effective inpreventingk sand, silt and other foreign substances from passing fromthe supply pipe upwardly through the tubular standard 17.

The upper portion of tubular standard 17 is provided with periorations22 and formed integral with and projecting upwardly from the tubular@standard immediately above these perforations isapostzs. Surroundingthe upper perforated portion of the standard V17 .is a housing 24 andprojecting carrying at its outer end a removable jet nozzle 26, whichisdesigned to discharge the main jet of water from the sprinkler; j

4 Screw-seated on thetubular standard 17, irnmediately below housing;24, is a ring 27 provided at. its upper'end witha flange 28 having aninclinedlupper surface and said 'ring 27 may be located' inrit-sadjustedposition upon Ythe threaded portion of standard lby means of aclampn ing screw 29 that passesY through vears 30 that project outwardlyfrom said ring and theY latter being split between said ears.

Screw-seated on thelower 'end of housing 24 is a ring 31having aA flange32 that prcjectstoward flange 23 and resting ontopof ange 32 is theouter portion of a packing ring or washer 33 of leather,-rubber orsuitable compositionand the `-inner portion of this packing ring restson the -inclined upper face of' ange 28.

Seated within the lower portion of housing 24 is a retaining ring 34that clamps the outerportion of vpacking ring 33 against 'liange 32. Y

Surroundingl the tubular post 17 and bearing directly on top of Vtheinner portion of packing ring 33 above flange 28 is a retaining ring 35of metal* and disposed on top thereof is a packing ring 86,y preferablyvof felt which surrounds the tubular postl and which isjretained inposition by an overlying ring'37 of metal. Y

Bearing on-top of the ring 37 lis the lower end of an expansive coilsprin'gii and which surrounds the perforated portion of pcst-17.'Screw-seated on the upper portion of tubular post 17, is'va ring 39which is heldr by a lock ring 40andbearing against the underiace of thisring 39, which is inclined, is the inner portion of a packing ring 41 ofleather, rubber or suitable composition. The outer portion of thispacking ring 'bears against an internal shoulder that is formed on thewallofhousing 24 and screw-se`ated within said housing and bearingagainst the outer portionv of said packing ring is aclainping ring`42,preferably of metal.

Bearing against the underside of the inner portion of thepacking ring41is a ring 43 of metal Vand positioned against the underside of this.ring Sra packing ring 44 of felt 0r analogous ma,- terial that `isenclosedan retainedin position by rinea. 'i Ik The inner and outer edgesof the retaining rings 35 and 43 are concentric with and spaced apartfrom tubular post 17 and the adjacent retaining rings 34 and 42, withthe result that there is no contact of metal between the tubular post 17and the metal rings that retain the packing rings 33 and 41 in properposition against the flanges 28 and 39. w

Theupper end of expansive spring 38 bears against the underside of theretaining ring 45.

Asa result of the construction just described, the'pressure of the Waterpassing through the chamber within housing 24 is directed equallyagainst the packing rings 33 and 41, with the result that uid pressuretight joints are produced between both ends of housing 24 and thetubular post 17 and the pressure exerted by coil spring 38 is alsoVeffective in producing and maintaining these tight joints.

Secured in any suitable manner to the inner face of the side wall ofhousing 24 are one or more vertically disposed plates 46 that functionas baffles to prevent the whirling of waterrduring its passagel throughthe chamber within said housing.' from the side 'thereof is a shortinclined tube 25 Detachably secured in any suitable manner on top ofhousing 24 is a gearhousing 47, the bottom plate of which is spaced ashort distance above the retaining ring 39 so that there is an open airspace 48 between the top of housing 24 andthe bottom of housing 47. Thisspace 48 permits any water that would otherwise tend to accumulate ontop ofthe flexible head of housing 24,-to be thrown outwardly bycentrifugal force away lfrom the sprinkler during the rotation of saidhead and.

the lparts carried thereby. Y

VFormed integral with the bottom wall of hous ing r47 and disposedconcentrically with vrespect to' post 23, which projectsV upwardly intothe chamber withinsaid housing, is an annular wall Positioned on thelower portion `of Athcfpost '23 is a bearing ring 50 against whichengages the upturned inner edge of ak packing ring 51 of leather oranalagous material and which ringA4 rests on the bottom plate of housing47y within the space encompassed by wall 49. The'upturned inner edgeofthis packing ring is caused tohug rthe bearing ring 50 by a splitcompression ring 52 that encircles said upturned inner edge.

Arranged within the wall 49 and resting on the outerpoition of packingring 51, is a spacing ring 53 and bearing on the top thereof is achannel shaped ring 54 that functions as a cup race `for a series ofball bearings 55.

yThe inner edge of ring 54 is spaced a slight distance apart from post23.

Screwseated on the intermediate portion -of post'23' is a conebearingring 56, the lower end results from the upward pressure o f an expansivecoil spring that is disposed be'twjeen'thie bearing at the upper end ofpostk 23 Aandthe top plate of the housing and which spring ishereinafter more ,fully described. p

Screw-seated in the upperend o i'wall 49 is the lower end o1" a collar60 and positioned `on aflange yno retained in position within the collar60 in any suitable manner.

By screwing collar 66 downward, pressure is `applied to parts 54, 53 and51 to maintain a tight joint between the anti-friction bearing in thelower portion of the gear housing 47.

Secured in any suitable manner to the ,upper vend of post 23, is a wormwheel 62, and they upper thelower portion of said ring ange and bearingon top of said bearing ring 64 is ythe lower'end of an expansive coilspring 68. The upper end of this spring bearing against a removable cap69,

`thatcloses the upper end of the chamber within ring flange 65. As aboveset forth spring 68 tends to lift the gear housing so as to maintain aproper bearing between cup race 54, bearing members 55 and cone bearing56 and to also maintain proper bearing between the upperend of standard23, bearing members 63 and the bearing cone 64.

Thus by the use of the expansive spring 68, the rotary head or housingpractically floats on its bearings while the sprinkler is in operation.

Secured to the upper portion of housing 47 on opposite sides thereof arethe lower ends of an inverted U-shaped handle 76, by means of which thesprinkler may be readily lifted and carried.

ends thereof against the anti-friction members I of the bearings 71.

Secured on this shaft 73 is a worm 75 that engages the yteeth of wormwheel 62.

Secured on shaft 73 is a worm wheel 76 that engages ,a worin 77 and thelatter being secured on a shaft 78 that is formed in two partstelescopically connected and the outer ends of said parts bearing insuitable anti-friction bearings in the side walls of housing 47.

A spring 79 is arranged between the two parts of shaft 78 formaintaining the cone bearing on the ends thereof in yielding engagementwith the anti-friction bearing at the ends of said shaft and this shaft78 is arranged below and disposed substantially at right angles to shaft73. L

Secured on shaft k78 is agear wheel 80 that meshes with a pinion 81V andthe latter being secured on a shaft 82 that is disposed slightly aboveand `to one side of shaft 78 and above and atright angles to shaft 73. Y

Shaft 82 is formed in two parts that are normally forced apart by an`expansion springV 83 in order to maintain the cone bearing rings 84that rvthe side walls of housing 17. One end of shaft vdrip off thegland or stuffing box and not pass therethrough.

the unseating of pin 92 and this cap is retained is located externallyof the wall of housing 47 and formed onrthe intermediate portion ofthehous'- ing of said gland or stuingbox is a circumferential ange 87that functions tooause water'to The two-part shafts 73 and 78 arearranged so that the thrustreceived by the worms carried by said shaftsis against the fixed cones on said shafts while the slip cones on theopposite ends of said shaftsfare retained against their bearings by theexpansive springs 74 'and 79 and shaft'82 and' its bearings are arrangedso that the yiixed cone S4 receives the outward thrust that is impressedon 'shaft 82 by the bladed wheel while the same is in motion and thusthe slip cone 84 is relieved of the thrust forces. i

All cones carried by the shafts 73, 78 and 82 are secured by pins to theparts of the shaftsso that said cones and shafts rotate together.

Extending diametrifally through shaft 82, just beyond the gland 86, is apin 87a and bearing thereagainst, is the central portion of a combineddriving and' water spreading wheel comprising a disc 88 that isprovidedon its inner focus adjacent toits outer edge with a series of blades orvanes 89 that receive a jet of water from a nozzle hereinafter morefully described and the impact or force of the water against theseblades or vanes imparts rotary motion to the wheel and to the shaft 82,upon which it is mounted.

Formed integral with and projecting inwardly from the disc 88 of thebladed wheel, is a ring flange 88a that encircles the gland 86 and theedge of said ring fiange surrounds flange 87. This ring flange iseffective is protecting the gland 86 againstthe inward passage of waterand foreign substances carried thereby for while the wheel is in motionany water that may passY inwardly along theY inner face thereof, will bekthrown radially outward by centrifugal force as it passes unto theoutward surface of said ring ange v888. Projecting outwardly from thecenter of this wheelY is a hub 90, in which is formed a diametricallyarranged slot 91 and occupying said slot is a pin 92 that passesdiametrically through shaft 82. v

Positioned upon hub is a cap 93, the flange of which overlies the endsof slot 91 to prevent in position on the hub 90 and the end of shaft 82by anut 94 that is screw-seated on the threaded end of said shaft. Bytightening nut 94 the central portion of the wheel is clamped'againstpin 87 and thus saidwheel is very firmly secured to shaft 82 and at thesame time it may be readily removed therefrom.

Seated in the side Wall of housing 24 on the same side` of the rotatinghead with the water compact and spreading wheel is the lower threadedend of an elbow'tting 95 and arranged between said fitting and the wallof the housing is a packing ring 96 against which bears a gland nut 97.

Screw-seated in the upper portion of AVthis el- A bow fitting is thelower portion of a vertically disposed tubularv member 98. and arrangedbe- Ytweenthe members 95 and. 98 is a packingring 99v against whichbears a gland nut 100.

The upperend of tubular member 98 terminates in a'horizontally disposedhead 19,1' and positioned against the open end of said head 101 istheopen lower end of'aV short tube 102. Removably seated in vtheoppositeend of: this short tube isajet nozzle 102EL that is adapted `to ds- 1rizo charge a jet of water against the blades 89 on ldisc 88.

.A packing ring 103 is interposed betweenthe contacting edges of thepartsl 101 and 102 and ksaid parts are connected by a horizontally disposed pin or bolt 104 on one end'of which is mounted a clamping nut 105,beneath which is disposed a suitable packing ring.

The construction just described enables the tube 102 and jet nozzle102at to be raised orlowered so as to regulate and control the lpoint ofyimpact between the jet of water that issues :from said nozzle and theblades or vanes 89.

A further adjustment of the jet nozzle toward `and away from the axis ofthe elbow tting Ais-,provided by screwing .the lower portion of tting 98into or out of the upper portion of elbow -tting 95 and locking `saidmember 98y after adjustment vby tightening gland nut 100.

Screw-seated in `thelower portion of the nt- -ting 95 vvdirectlyopposite the leg that is screwseated inthe lWall of housing 24, is atubular plug 106 closed at its inner end vby a plate or disc 107 andlocated between this plug and the wall of fitting 95 is a packing .ring108 that is retained in .position by a nut 109 that is screwseated ontheouter portion of said plug.

. This plug functions as an adjustable `pressure regulator to control`the volume flow of water from housing 24 through the elbow tting 95,tubular member 98, tube 102 and jet nozzle 1028L and saidadjustable plugis locked after adjustment, by tighteningnut 109.

Seated in thewall of fitting 95, just above the pressure regulating plug106, is a removable plug 110, which when removed permits a pressuregauge to be inserted into fitting 95 to ascertain the pressure of thewater passing therethrough and-thus yielding the requirement foradjustment .of plug 106.

In the operation of my improved sprinkler, water enters housing 10through supply line 14 and after passing through strainer 21 andapertures 20, said water passes upward through tubular member 17 and outthrough apertures y22 to the chamber within housing 24.

From housing 24 water passes through upwardly inclined tubular member 25and `discharges through jet nozzle 26 and. this jet of water -isdistributed throughout a wide radius, as the head or housing rotates onthe upper portion of tubular standard 17.,

`The Water passing through housing 10 is strained as it passes throughthe strainer 21 and fall sand, silt and other foreign matter that cannotpass through this strainer, accumulates in the settling chamber 16 andmay be removed frornvtime to time by removing plug 15 that normallycloses the cleanout opening.

The pressure of the water passing through the chamber in housing 24 isapplied uniformly to vthe 4packing rmembers that close the upper andlower lends of said chamber and this pressure is effective in forcingthe flexible packing members 33-and 41 outwardly against the flanges 28and 39 and during the rotation of the housing serve as bearing membersare protected against comparatively rapid wear which would otherwiseresult .if they were subjected to the action of sand, slit or the like.

Water from the chamber withinrhousing 24 passes through elbow fitting95, tubular member 98, tube 102 and jet nozzle 102 and the jet of Waterthat discharges from this nozzle, impinges .against the blades or vanes89 on the water spreading wheel, thereby imparting rotary motion to saidwheel and its shaft 82 upon which said wheel is mounted.

The blades or vanes 89 are shaped so that they will deflect and throwthe water that strikes against them, outwardly for a considerable areaimmediately adjacent to the sprinkler and which i area is not covered bythe water that discharges from jet nozzle 26. As a result of thisarrangement the entire area of the ground surface immediately adjacentto the sprinkler receives water from said sprinkler while the same is inoperation.

As heretofore stated, the volume flow and pressure of water throughelbow fitting 95, tubular member 98 and jet nozzle 102BL may beaccurately controlled and regulated by proper manipulation of plug 106and the degree of pressure discharging through this jet nozzle may bereadily ascertained by connecting a suitable pressure gaugeto theopening that is normally closed by plug 110. 11,.

After shaft 82 is rotated as a result of the imp 'ngement of the jet ofwater from nozzle 102 against varies or blades 89, pinion `81, meshingwith gear wheel 80, imparts rotary motion to shaf 7S and through worm 77and worm wheel 76 this rotary motion. is imparted to shaft 73.

Worm 75, carried by shaft 73, engages worm wheel 62, but is secured onthe upper end of Ypost 23 and as a result housing 47 and parts carriedthereby is caused to rotate about the axis formed by post 23 and tubularstandard 17 and during such rotation, said housing 47 is `supportedbythe anti-friction bearings 55 and 63.

The pressure of the water within the chamber in housing 24 is equalizedagainst the packing-elements at both ends of said water chamber and thespring 68 that is interposed between the upper one of the anti-frictionbearings in the gear chamben' tends to equalize the pressure upon saidbearings with the result that the entire head or housing and partscarried thereby rotate freely upon the axis formed by the tubularstandard 17 and post 23 and the only metal to metal contact vbetween theflXed and rotating parts are the Vcone bearings, races and anti-frictionmembers that y,

function as anti-friction lbearings between the housing and the axisthereof. Y

The chamber within housing 47 islled, or partially filled with grease ora heavy liquid lubricant, thereby providingample lubrication for all 1L.

operating .parts within said housing.y

The felt lpacking ring 61 contained within the upper portion of member60 prevents the dust and grit from passing downwardly into the chamberoccupied by the anti-friction bearings 55 and the Il- Vbearing parts`that cooperate therewith.

Thus the head comprising the housing 24 and 27 (which are separated byan open airspace) is rotated upon the'tubular standard 17 and post'23and the jet of Water issuing from jet nozzle 26 and the water .thatdischarges from `jet nozzle 102a `(which is distributed by the bladedwheel) is distributed throughout an area of considerable radius withthesprinkler as a center.

In assembling and adjustingthe rotary head tween the water chamberand-the support upon for operation, the bearing ring 56 is screweddownward into annular wall 49 until balls 55 are engaged and when suchengagement takes place, the entire head or housing is lowered to aslight degree so as `to properly adjust the packing ring 41 s0 that theinwardly projecting portion thereof lies smooth and flat againstthevunderside of ring 39. f

Thislowering of the housing also properly adf justs the inwardlyprojecting portion of ring 33 so that it lies smooth and flat uponflange 28. The parts 28, 32, 39 andl the'ange against which the outeredge of-packing ring fil engages are constructed so that when theirouter faces align with each other or occupy the same horizontal planes,the packing rings 41 and 33 are properly positioned so as to operate athighest eiciency and produce the desired watertight joints at the endsof the water chamber within housing 24. 1 Y

Thus it will be seen that I have provided a rotary sprinkler having arotary head within-which are formed separate water and gear chambers,with a main jet nozzle projecting from the water chamber and with thegear chamber containing 4 the necessary gearing for imparting rotarymotitl tion to the head.

The rotary head is mounted on a post or standard so as to rotate thereonwith minimum friction and there is no metal contact in the bearingsbewhich the housing rotates. v-

The iiexible packings at both ends of the water chamber are acted uponby the pressure of the water passing through said chamber and the entirebearing of the rotary head uponvthe standard is carried by anti-frictionbearings that are disposed within the gear housing and which latter isfilled with heavy oil or grease to facilitate thel operation of thegears and operating parts within the gear compartment. i

The water chamber and gear chamber, although connected to each other areseparated by an open air space and the joints between the i post orstandard and the water and lgear hourings are packed so as toeffectually prevent water from entering the gear-chamber and likewisefor preventing grease or oil from entering Vthe water chamber.

When the sprinkler is not in use, the iiexiblc packing elements at theends of the-water chamber are rrnly held in place and in proper positionby spring pressure and thus said parts are retained in position so as tofunction properly when the sprinkler is subsequently operated.

A further feature of my invention is, the Yprovision of relativelysimple and effective means for regulating the pressure of the water thatdischarges in jet form unto the bladed wheel and kthe means forregulating this pressure is located in the elbow tting that leads fromthe water chamber so that said pressure regulation is entirelyindependent 'of the pressure of the water that'discharges through themain nozzle 26.

A further feature of my invention is, the wide ,range of adjustabilityof the jet nozzle that diand said head while in operation practically 'aspring arranged between-said standard and 'head for yieldinglysupporting the latter, there "of'thefwater chamberandsaid standard, ajet nozzle projectingfrornthe water chamber, antifriction bearingsarranged within thef gear chambladed wheel connected-to said drivinggear coniioats on its bearings with a minimum of friction and verylittleif any wear.
